The one or more keywords are incorporated into a model that includes a plurality of keywords and describes, at least in part, a topic of a group instant messaging session among the plurality of client devices. At least one of (i) the model and (ii) instructions describing how to update the model are distributed to the plurality of client devices.

TECHNICAL FIELD

The present invention relates generally to the field of instantmessaging, and, more particularly, to summarizing and visualizinginformation relating to a topic of discussion in a group instantmessaging session.

BACKGROUND OF THE INVENTION

Instant messaging (IM) is a type of communication that offers real-timetext transmission over a network, such as the internet. Short messagesare typically transmitted bi-directionally between two parties, wheneach user chooses to complete a thought and select “send”. Some IMapplications can use push technology to provide real-time text, whichtransmits messages character by character, as they are composed. Instantmessaging systems tend to facilitate connections between specified knownusers (often using a contact list also known as a “buddy list” or“friend list”). Depending on the IM protocol, the technical architecturecan be peer-to-peer (direct point-to-point transmission) orclient-server (a central server retransmits messages from the sender tothe communication device). More advanced instant messaging can add filetransfer, clickable hyperlinks, Voice over IP, or video chat.

Natural language processing is a field of computer science, artificialintelligence, and linguistics concerned with the interactions betweencomputers and human (natural) languages. As such, natural languageprocessing is related to the area of human-computer interaction. Manychallenges in natural language processing involve natural languageunderstanding—that is, enabling computers to derive meaning from humanor natural language input. Natural language processing can be combinedwith speech recognition to derive meaning from spoken language.

Speech recognition is the translation of spoken words into text. Speechrecognition is referred to as automatic speech recognition, computerspeech recognition, or “speech to text”. Some speech-recognition systemsuse “speaker-independent speech recognition” while others use “training”wherein an individual speaker reads sections of text into the speechrecognition system. These systems analyze the person's specific voiceand use it to fine-tune the recognition of that person's speech,resulting in more accurate transcription. Systems that do not usetraining are called “speaker-independent” systems, whereas, systems thatuse training are called “speaker-dependent” systems. Speech-recognitionapplications can include voice user interfaces such as voice dialing,call routing, simple data entry, preparation of structured documents,speech-to-text processing, and direct voice input.

DETAILED DESCRIPTION

Embodiments of the present invention recognize that group instantmessaging sessions can contain information about multiple topics,thereby presenting a challenge for participants who want to quickly andeasily identify information regarding a specific topic of discussion. Inaddition, group instant messaging sessions (i.e., group IM sessions) canvary greatly in the number of participants, the amount of informationexchanged, and the amount of time during which the group IM sessiontakes place. For example, a session may consist of a single message froma first person and quick replies from a second person and a thirdperson. In another example, a session may include many participants(e.g., more than three participants) discussing multiple topics overmany hours. A user must often scroll through an entire history orsection of chat messages in order to find information relevant to aspecific topic of discussion (e.g., scheduling a social event).Furthermore, if one or more participants are using voice messages, auser may need to listen to each voice message, in sequential order, inorder to fully comprehend the discussion.

Embodiments of the present invention provide for summarizing andvisualizing information related to a topic of discussion in a group IMsession. Various embodiments summarize and visualize informationrelating to a topic of discussion based, at least in part, on one orboth of natural language processing (NLP) logic and speech recognitionlogic.

Embodiments of the present invention will now be described in detailwith reference to the Figures. FIG. 1 is a functional block diagramillustrating a computing environment, in accordance with an embodimentof the present invention. For example, FIG. 1 is a functional blockdiagram illustrating computing environment 100. Computing environment100 includes communications server 130, client device 110A, clientdevice 110B, and client device 110C, all communicatively connected vianetwork 120. Client devices 110A, 110B, and 110C are collectivelyreferred to as client devices 110 herein. While the embodiment depictingFIG. 1 includes three client devices that are communicatively connectedto communications server 130, the number of client devices 110 to whichcommunications server 130 can communicatively connect to at any one timeis not a limitation of the present invention. Accordingly,communications server 130 can communicatively connect to a greater orlesser number of client devices 110 than are depicted in FIG. 1 and thegroup IM sessions described herein with respect to FIGS. 2A-2D and3A-3H.

In various embodiments, each of client devices 110 is a computing devicethat can be a standalone device, a server, a laptop computer, a tabletcomputer, a netbook computer, a personal computer (PC), a desktopcomputer, a personal digital assistant (PDA), a smart phone, or anothertype of programmable electronic device. In some embodiments, clientdevices 110 are a collection of different types of computing devices. Inother embodiments, each of client devices 110 represents a computingsystem utilizing clustered computers and components to act as a singlepool of seamless resources. In addition, each of client devices 110includes a user interface (UI) by which a user can provide user input toa respective client device. In general, each of client devices 110 canbe any computing device or a combination of devices that is capable of:communicating with other client devices of client devices 110; accessingcommunications server 130 and/or executing code that provides, at leastin part, the functionality provided by communications server 130, asdescribed herein; and providing a user interface, as described herein(e.g., user interfaces 112). Client devices 110 can include internal andexternal hardware components, as depicted and described in furtherdetail with respect to FIG. 5.

Client devices 110A, 110B, and 110C respectively include user interface112A, user interface 112B, and user interface 112C. User interfaces112A, 112B, and 112C are collectively referred to as user interfaces 112herein. User interfaces 112 execute locally on respective client devicesand operate to provide user interfaces to users of the respective clientdevices. User interface 112A, for example, enables a user of clientdevice 110A to communicate with users of client device 110B and/orclient device 110C and provides data to communications server 130 foranalysis by group IM session analysis software 132, as described herein.In some embodiments, user interface 112A is stored on client device110A. In other embodiments, user interface 112A is stored on anothercomputing device (e.g., communication server 130), provided that clientdevice 110A can access and is accessible by group IM session analysissoftware 132. Similarly, user interfaces 112B and 112C can be storedlocally or remotely. Persons of ordinary skill in the art willunderstand that, in general, a user interface is optimized for thecomputing device on which it is presented, and accordingly, userinterfaces 112A, 112B, and 112C can differ from one another based, atleast in part, on the types of computing devices on which they arepresented (i.e., the type(s) of computing devices that variouslydescribe client devices 110A, 110B, and 110C).

Network 120 can be, for example, a local area network (LAN), a wide areanetwork (WAN) such as the Internet, or a combination of the two, and mayinclude wired, wireless, fiber optic or any other connection known inthe art. In general, network 120 can be any combination of connectionsand protocols that will support communication among client devices 110and between client devices 110 and communication servers 130.

Communications server 130 is a computing device that can be a standalonedevice, a wearable computing device, a server, a laptop computer, atablet computer, a netbook computer, a personal computer (PC), or adesktop computer. In some embodiments, communications server 130represents a computing system utilizing clustered computers andcomponents to act as a single pool of seamless resources. In general,communications server 130 can be any computing device or a combinationof devices with access to and/or capable of executing group IM sessionanalysis software 132, with access to database 134, and provided that itcan access and is accessible by client devices 110. In the embodimentdepicted in FIG. 1, group IM session analysis software, database 134,and group IM session model 136 reside on communications server 130. Inother embodiments, one or more of group IM session analysis software132, database 134, and group IM session model 136 can reside on variousother computing devices, provided that each resource can access theother resources and provide the functionality described herein. In yetother embodiments, one or both of group IM session analysis software132, database 134, and group IM session model 136 can be storedexternally and accessed through a communication network, such as network120.

Database 134 is a data repository that may be written to and/or read bygroup IM session analysis software 132 and client devices 110. In someembodiments, database 134 can be written to and read by programs andentities outside of computing environment 100 in order to populatedatabase 134 with data. In general, database 134 can store one or more:IM messages, text mining rules, NLP rules, speech recognition rules,group IM session models, IM topic templates, records of group IM sessionsessions, or any combination of these or other types of data related tosummarizing and visualizing topics of group IM session sessions.

In the embodiment depicted in FIG. 1, database 134 stores group IMsession model 136. Group IM session model 136 is data and metadata thatdescribes a visualization of a group IM session (i.e., a group IMsession) topic and is updated based, at least in part, on operations ofgroup IM session analysis software 132, as described herein. In otherembodiments, one or more versions of group IM session model 136 arestored on client devices 110 (e.g., a version of group IM session model136 stored on a first type of client device can differ from a version ofgroup IM session model 136 stored on a second type of client device). Inyet other embodiments, database 134 stores a version of group IM sessionmodel 136 and one or more of client devices 110 store respectiveversion(s) of group IM session model 136 that are based, at least inpart, on the version of group IM session model 136 that resides indatabase 134. In various embodiments, whether or not a particular clientdevice of client devices 110 accesses a remotely stored version of groupIM session model 136 or a locally stored version of group IM sessionmodel 136 is based, at least in part, on the computing capabilities ofthe particular client device (e.g., on the relative “thickness” or“thinness” of the particular client device). A client device thataccesses a remotely stored version of group IM session model 136 canaccess group IM session model 136 at periodic intervals in time and/orin response to receiving a notification from communications server 130that group IM session model 136 has been updated. Client devices thataccess a locally stored version of group IM session model 136 can updatethe locally stored version of group IM session model 136 based, at leastin part, on a comparison of the locally stored version with a remotelystored version and/or instructions received from communications server130.

For descriptive simplicity, group IM session model 136 is a model of asingle group IM session, and client devices 110 represent client devicesthat are participating in the group IM session that is described, atleast in part, by group IM session model 136. Other groups of clientdevices participating in various group IM sessions can, however, connectto communications server 130 over network 120 and database 134 can storegroup IM session models that describe, at least in part, theseadditional group IM sessions. Persons of ordinary skill in the art willunderstand that is possible for a single client device to participate inmore than one group IM session.

In the embodiment depicted in FIG. 1, group IM session analysis software132 resides on communications server 130. In other embodiments, one ormore client devices of client devices 110 execute respective instancesof group IM session analysis software 132 in addition to, or as analternative to, an instance of group IM session analysis software 132that executes on communications server 130. Persons of ordinary skill inthe art will understand that natural language processing, speechrecognition, and other capabilities of group IM session analysissoftware 132, as described herein, generally require significantcomputational resources. Accordingly, whether or not it is advantageousto execute group IM session analysis software 132 on one on or more ofclient devices 110 is based, at least in part, on the computationalcapabilities of client devices 110.

Group IM session analysis software 132 operates to identify and manageinformation within a group IM session based, at least in part, onpredefined criteria relevant to a specific group IM session (e.g.,keyword types of an IM topic template selected by a user of one ofclient device 110, as described herein). In various embodiments, groupIM session analysis software 132 employs one or both of natural languageprocessing and text mining to summarize and visualize a topic of a groupIM session. In various embodiments, group IM session analysis software132 can receive voice message(s) and, using speech recognition,translate the voice message(s) into text-based message(s). Thecapabilities of group IM session analysis software 132 are discussed ingreater detail with respect to FIGS. 2A-2D, FIGS. 3A-3H, and FIG. 4.

FIGS. 2A-2D depict a user interface that is updated based, at least inpart, on instant messages exchanged in a group IM session and a model ofthe group IM session, in accordance with an embodiment of the presentinvention.

More specifically, FIG. 2A is a schematic diagram depicting an exampleof a user interface of a client device within the computing environmentof FIG. 1, in accordance with an embodiment of the present invention.For example, user interface 200 is a user interface of a smartphone thatis one of client devices 110. User interface 200 includes message window202, recipient field 207, message box 208, send button 210, menu 212,and archive shortcut icon 214. In the embodiment depicted in FIGS.2A-2D, message window 202 is divided (e.g., by a separator bar) intotopic summary pane 204 and message dialogue pane 206. Message dialoguepane 206 is a field that can display information relating to a group IMsession. For example, message dialogue pane 206 can display text, icons,or images communicated among client devices 110. Topic summary pane 204displays information based on operations of group IM session analysissoftware 132 in order to visualize and summarize a topic of the group IMsession displayed, at least in part, in message dialogue pane 206. Invarious embodiments, topic summary pane 204 can display text, icons,pictures, diagrams, or a combination thereof.

User interface 200 also includes various controls for initiating andparticipating in a group IM session. For example, recipient field 207 isa text field that presents the intended recipients of a message sent bythe client device on which user interface 200 executes. Stateddifferently, recipient field 207 identifies target client devices basedon associations between the target client devices and specific people.As used herein, “target client devices” are the client devices that,excluding the client device on which user interface 200 executes,comprise client devices 110. In FIGS. 2A-2D, for example, recipientfield 207 indicates that the target client devices are client devicesthat are respectively associated with users A, B, C, D, E, and F. Insome embodiments, like the embodiment depicted in FIGS. 2A-2D, recipientfield 207 includes information that identifies the user of the clientdevice on which user interface 200 executes. In other embodiments,recipient field 207 excludes information that identifies the user of theclient device on which user interface 200 executes. In variousembodiments, hovering and/or clicking on recipient field 207 activates adialogue box and/or a menu with which a user can designate target clientdevices (e.g., to initiate a group IM session or to add newparticipants).

Message box 208 is a dialogue box into which a user of one of clientdevices 110 can input text in order to communicate the information toother client devices of client devices 110. In some embodiments, theuser can also input various icons into message box 208 (e.g., emoji).Send button 210 is a button that the user can activate in order totransmit, over network 120, information in message box 208 tocommunications server 130 and/or client devices 110.

Menu 212 is one example of a menu that enables the user to, among otherthings, activate and inactivate a “balloon assistant mode.” At least inpart, activating the “balloon assistant mode” instructs a computingdevice, such as communications server 130, to analyze communicationsbetween client devices 110 using group IM session analysis software 132.In general, only one instance of the balloon assistant mode can beactive at a time in any one group IM session. As used herein, an“initiating client device” and an “initiator” respectively refer to aclient device and a user of the client device that activates the balloonassistant mode. Once an initiator of a first instance of the balloonassistant mode deactivates the first instance of the balloon assistantmode, the initiator of the first instance or a user of another clientdevice can initiate a second, sequential instance of the balloonassistant mode as an initiator of the second instance. In variousembodiments, a user can hover and/or click on archive shortcut icon 214to activate a resource (e.g., a menu and/or dialogue box) that enablesthe user to view resolutions to previous instance(s) of the balloonassistant mode, as described herein.

In FIGS. 2A-2D, user 216 (i.e., user A) is a user of the client deviceon which the depicted instance of user interface 200 executes. Morespecifically, FIG. 2B depicts an example of user interface 200 afteruser 216 has initiated a group IM session but has not activated theballoon assistant mode, in accordance with an embodiment of the presentinvention. In this example, message 218 is sent to the target clientdevices identified in recipient field 207 and is presented in messagewindow 202 of user interface 200. In the embodiment depicted in FIG. 2B,message window 202 is not divided into topic summary pane 204 andmessage dialogue pane 206, as depicted in FIG. 2A, until the balloonassistant mode is activated. User 216 can activate the balloonassistance mode by selecting the “Activate balloon assistant mode”option from menu 212.

In various embodiments, activating the balloon assistant mode activatesone or more menus or dialogues through which an initiator (e.g., user216) can configure, at least in part, group IM session analysis software132. As described herein, group IM session analysis software 132utilizes natural language processing and/or text mining to analyzemessages in a group IM session. The initiator can advantageouslyoptimize group IM session analysis software 132 by selecting from amonga plurality of predefined IM topic templates, customize a predefined IMtopic template, create a new IM topic template, or otherwise describe atopic of discussion in a group IM session. For example, selecting an“appointment” IM topic template optimizes group IM session analysissoftware 132 by, at least in part, instructing group IM session analysissoftware 132 to extract, using natural language processing and/or textmining algorithms, keywords relating to “when” the appointment willoccur, “where” the appointment will occur, and “what” the appointment isfor.

The aforementioned “when,” “where,” and “what” are example of types ofkeywords (i.e., keyword types). An “appointment” can be a social,personal, or professional engagement. In another example, selecting an“action” IM topic template instructs group IM session analysis software132 to extract keywords relating to “who” the action involves, “when”the action will occur, when an action is “due” or “expected” to occur,and “what” the action involves. In yet another example, a user creates acustom IM topic template by selecting one or more keyword types (e.g.,“who,” “what,” “when,” and/or “where”) from among a list of keywordtypes. In addition, keyword types can be subdivided into two or morekeyword sub-types. For example, an IM topic template can include “date”and “time” keyword sub-types to describe a group IM session including adiscussion of “when” something (e.g., an appointment) will occur withmore accuracy (e.g., a user can customize the “appointment” IM topictemplate by subsiding the “when” keyword type). In other embodiments,however, an initiator can activate the balloon assistant mode withoutselecting an IM topic template. For example, an initiator may choose notto select an IM topic template to save time and/or because predefined oruser-created IM topic templates are not adequate to describe an intendedtopic of discussion in a group IM session. In yet other embodiments,group IM session analysis software 132 automatically selects anappropriate IM topic template based, at least in part, on a message inmessage window 202 (e.g., message 218).

FIG. 2C depicts the example depicted in FIG. 2B following the activationof the balloon assistant mode and a selection of an IM topic template,in accordance with an embodiment of the present invention. Followingactivation of the balloon assistant mode, user interface 200 subdividesmessage window 202 into topic summary pane 204 and message dialogue pane206. User interface 200 presents message 218 and an identifierassociated with user 216 in message dialogue pane 206. User interface200 presents balloon 220, balloon 222, and balloon 224 in topic summarypane 204. In the embodiments depicted in FIGS. 2C and 2D and FIGS.3A-3H, user interface 200 presents various “balloons” as speech bubbles.In other embodiments, however, user interface 200 can present balloonsas thought bubbles and/or balloons having polygonal shapes, circularshapes, ovular shapes, or other types of shapes. In general, “balloon”refers to any icon that can present (i.e., include text of) one or morekeywords on user interface 200. In addition, user interface 200 canpresent balloons including different shapes in topic summary pane 204(e.g., each keyword type is associated with a specific shape of balloon)and/or balloons can differ in size (e.g., the “top-ranked” balloon, asdescribed herein, can be larger than lower-ranked balloons). Similarly,balloons can be presented in one or more colors (e.g., each keyword typeis associated with a specific color of balloon). In some embodiments,the shape(s), size(s), and/or color(s) of the balloons areuser-configurable settings of user interface 200. In other embodiments,the initiator can determine how user interfaces 112 present balloons onclient devices 110. In yet other embodiments, the shape(s), size(s),and/or color(s) of the balloons are properties of group IM session model136 and are not user-configurable settings.

In the example depicted in FIG. 2C, user 216 selected an “appointment”IM topic template based, at least in part, on message 218 (i.e., amessage asking the group IM session participants to help plan a socialengagement). Accordingly, balloon 220 is associated with a “when”keyword type, balloon 222 is associated with a “where” keyword type, andballoon 224 is associated with a “what” keyword type. Based, at least inpart, on the selected IM topic template and message 218, group IMsession analysis software 132 analyzes message 218 and constructs groupIM session model 136, as described herein. In this example, group IMsession analysis software 132 extracts the keywords “Sunday” and “Movie”from message 218 and includes these keywords in group IM session model136. User interface 200 presents information in topic summary pane 204in accordance with group IM session model 136. Accordingly, balloon 220includes the keyword “Sunday” and balloon 224 includes the keyword“Movie.” In the embodiment depicted in FIG. 2C, user interface 200presents balloon 222 in topic summary pane 204 even though the group IMsession does not include a keyword relating to the “where” keyword type(i.e., a “blank balloon”). In other embodiments, user interface 200 doesnot present balloons in topic summary pane 204 until the group IMsession includes at least one keyword of respective keyword type(s).

FIG. 2D depicts the example depicted in FIG. 2B following the activationof the balloon assistant mode and without a selection of an IM topictemplate, in accordance with an embodiment of the present invention. InFIG. 2D, user interface 200 presents balloon 226 in topic summary pane204. Balloon 226 includes all of message 218. In some embodiments, likethe embodiment depicted in FIG. 2D, group IM session analysis software132 identifies potential keywords and constructs group IM session model136 such that user interface 200 can identify the potential keywords(e.g., by underlining, italicizing, or highlighting) in balloon 226. Inother embodiments, user interface 200 does not identify potentialkeywords based on group IM session analysis software 132 and group IMsession model 136. In general, users of client devices 110 can vote, asdescribed herein, on balloons that are not associated with a keywordtype (e.g., balloon 226) in the same manner as balloons 220, 222, and224 in order to reflect preferences with respect to a topic ofdiscussion in the group IM session.

FIGS. 3A-3H depict a topic summary pane or message dialogue pane aspresented on a user interface at various points in a group IM session,in accordance with an embodiment of the present invention. Morespecifically, FIGS. 3A, 3D, and 3F depict group IM session 300 inmessage dialogue pane 206 and FIGS. 3B, 3C, 3E, 3G, and 3H depictinstance 302 of the balloon assistant mode, as presented in topicsummary pane 204.

Group IM session 300, as depicted in FIG. 3A, includes messages fromuser 216 (i.e., user A), user 230 (i.e., user B), user 234 (i.e., userC), and user 238 (i.e., user D). As in the example discussed withrespect to FIGS. 2B-2D, user 216 is the initiator of instance 302 of theballoon assistant mode. Similarly, message 228 is analogous to message218 and requests that participants in group IM session 300 discuss plansfor a social engagement. Accordingly, instance 302 of the balloonassistant mode utilizes the “appointment” IM topic template discussedwith respect to FIG. 2C. User 230 responds to message 228 with message232, indicating agreement with the proposal presented in message 228.User 234 responds to message 228 with message 236, similarly indicatingagreement with at least the “when” of the proposal presented in message228. User 238 responds to message 228 with message 240. Unlike messages232 and 236, message 240 indicates disagreement with the “when,”“where,” and “what” of the proposal presented in message 228 andproposes an alternative (i.e., meeting for dinner, at Le Grill, onFriday).

Group IM session analysis software 132 constructs group IM session model136 upon initiation of instance 302 of the balloon assistant mode anditeratively updates group IM session model 136 in response to analyzingeach message in group IM session 300, as described in greater detailwith respect to FIG. 4. FIG. 3B depicts instance 302 of the balloonassistant mode as presented in topic summary pane 204 after group IMsession model 136 is updated based, at least in part, on message 240. InFIG. 3B, topic summary pane 204 includes balloons 304, 306, 308, 310,and 312. Balloons 304 and 306 are associated with a “when” keyword type,balloon 308 is associated with a “where” keyword type, and balloons 310and 312 are associated with a “what” keyword type. In general, therelative positions of balloons that are associated with the same keywordtype is based on the number of “votes” for the keywords associated withthe respective balloons. The “top-ranked” balloons are the balloon that,for each keyword type, receive the most “yes” votes. In variousembodiments, the top-ranked balloons are presented above and/oron-top-of lower ranked balloons. In some embodiments, a balloonincluding one or more keywords is presented for each keyword type, andkeywords are positioned (i.e., ordered or ranked) above or below otherkeywords based on votes, as described herein. In the example depicted inFIG. 3B, balloons 304, 308, and 310 are the top-ranked balloons. In someembodiments, group IM session analysis software 132 registers votes fora keyword based on message(s) in the group IM session. In group IMsession 300, for example, group IM session analysis software 132registers “yes” votes for balloons 304 and 310 based on messages 228,232 and 236. More specifically, group IM session analysis software 132registers “yes” votes for both of balloons 304 and 310 in connectionwith user 216 and user 230, respectively, based on message 228, fromwhich the respective keywords were extracted, and message 232, whichindicates general agreement with the proposal in message 228. Message236, however, is more ambiguous and open to interpretation. In variousembodiments, whether group IM session analysis software 132 registers a“yes” vote, a “no” vote, or a “neutral” vote (i.e., neither a “yes” votenor a “no” vote) for a balloon in connection with user 234 is based, atleast in part, on one or more semantic voting thresholds. Becausemessage 236, for example, can be interpreted as indicating agreementwith the “when” (i.e., Sunday), but not the “what” (i.e., High Tea),proposed in message 228, semantic voting threshold(s) can be set suchthat group IM session analysis software 132 registers a “yes” vote foronly balloon 304. Similarly, semantic voting threshold(s) can be setsuch that message 236 is interpreted as being neutral towards the “what”keyword type or as a “no” vote against balloon 310 (i.e., High Tea). Invarious embodiments, one or more semantic voting thresholds are based,at least in part, on setting(s) configured via user interface 200. Insome embodiments, one or more semantic voting thresholds are not basedon setting(s) configured via user interface 200.

In the example depicted in FIG. 3A, message 240 proposes alternatives tothe idea proposed in message 228. Group IM session analysis software 132recognizes that “dinner” is a keyword that should be associated with the“what” keyword type, that “Le Grill” is a keyword that should beassociated with the “where” keyword type, and that “Friday” is a keywordthat should be associated with the “when” keyword type. Group IM sessionmodel 136 and user interfaces 112 are updated accordingly (i.e.,balloons 306, 308, and 312 are added to topic summary pane 204). Inaddition, group IM session analysis software 132 registers one “yes”vote for each of balloons 306, 308, and 312 in connection with user 238.Group IM session analysis software 132 also recognizes that “Sorry, I'mbusy Sunday” indicates disagreement with the day proposed in message 228and registers a “no” vote for balloon 304 in connection with user 238.In some embodiments, a “yes” vote for a keyword of a keyword type causesgroup IM session analysis software 132 to register “no” votes for anyother keyword of the same keyword type. In other embodiments, group IMsession analysis software 132 recognizes that a “yes” vote for a keywordindicates that a user is merely “neutral” towards other keywords of thesame keyword type and will register “no” votes if, in the future, theuser indicates disagreement with other keywords of the same keywordtype. User 234, for example, can vote “no” for balloon 306 afterreceiving message 240 if group IM session analysis software 132recognizes that user 234 is merely “neutral” to balloon 306, even thoughvarious embodiments of group IM session analysis software 132 would haveregistered a “yes” vote for balloon 304 in connection with user 234based on message 236. In general, users of client devices 110 canchanges their votes with respect to a particular keyword, but the userscan only vote “yes” for one keyword in a keyword type and can only vote“no” once for each keyword. Requiring users of client devices 110 toaffirmatively vote “no” can, however, advantageously enable the users tovote down alternative proposals (i.e., various keywords) that they donot agree with (i.e., demonstrate a preference for alternatives/keywordsthat they are merely “neutral” to over alternatives/keywords that theydisagree with or are otherwise opposed to).

In addition, some embodiments include an opposition limit threshold thatcan be set via user interface 200 and/or is a predetermined setting ofgroup IM session analysis software 132. If the number of “no” votes withrespect to a keyword exceeds the opposition limit threshold, group IMsession model 136 is updated such that user interfaces 112 of clientdevices 110 do not present the respective keyword (e.g., a respectiveballoon is removed from topic summary pane 204).

In other embodiments, users of client devices 110 can vote “yes” for akeyword by dragging a respective balloon up (e.g., using atouch-sensitive screen or pad, a mouse, or another type of input device)relative to other balloon(s). In such embodiments, users of clientdevices 110 can similarly vote “no” for a keyword by dragging arespective balloon down relative to other balloon(s). Votes registeredin this manner are communicated to communications server 130 and/orother client devices of client devices 110 in order to update group IMsession model 136. In yet other embodiments, votes are registered based,at least in part, on either of analyses of messages via group IM sessionanalysis software 132 or by users of client devices 110 draggingballoons on user interfaces 112.

In the example depicted in FIG. 3C, users of client devices 110 can viewthe votes associated with a keyword by hovering and/or clicking on arespective balloon. In embodiments like the one depicted in FIG. 3C,user interface 200 identifies the users that voted “yes” and “no” (andin some embodiments, “neutral”) on the respective balloon. For example,hovering over balloon 304 “flips over” balloon 304 to reveal that users216, 230, and 234 votes “yes” for Sunday and that user 238 voted “no”Sunday, as described herein.

In the embodiment depicted in FIG. 3D, group IM session analysissoftware 132 includes speech-recognition algorithms that enable group IMsession analysis software 132 to translate audio messages into textmessages. User interfaces 112, of which user interface 200 representsone instance, present the translated messages within group IM session300, as depicted in FIG. 3D. For example, message 244 from user 242,message 246 from user 216, and message 250 from user 248 are voicemessages that group IM session analysis software 132 converted to textmessages.

In addition, group IM session analysis software 132 recognizes messagesthat are not relevant to the topic associated with a current instance ofthe balloon assistant mode based, at least in part, onspeech-recognition algorithm(s); a selected IM topic; a message from aninitiator (e.g., message 228) and any subsequent, related message(s)(e.g., messages 232, 236, and 240); or any combination of theaforementioned options. Group IM session analysis software 132 ignoresmessages that are not relevant to the topic associated with the currentinstance of the balloon assistant mode. Accordingly, group IM sessionmodel 136 does not reflect these unrelated, ignored messages. Forexample, group IM session analysis software 132 recognizes that messages244 and 246 are not related to instance 302 of the balloon assistantmode and ignores them.

FIG. 3E depicts instance 302 of the balloon assistant mode, as presentedin topic summary pane 204, after group IM session model 136 is updatedbased, at least in part, on message 250. Message 250 proposes anadditional alternative proposal. In this example, message 250 proposesthat the participants in group IM session 300 meet for a movie at the“Central Cinema” on “next Sunday.” User interface 200 ads balloons 314,318, and 316 to topic summary pane 204 based, at least in part, onmessage 250. Balloon 314 presents “Next Sunday” and is associated withthe “when” keyword type. Balloon 318 presents “Central Cinema” and isassociated with the “where” keyword type. Balloon 316 presents “Movie”and is associated with the “what” keyword type. Group IM session model132 registers, in connection with user 248, “yes” votes for balloons314, 316, and 318 accordingly. In various embodiments, like theembodiment depicted in FIG. 3E, balloons having the same number of “yes”votes are ranked in chronological order with earlier created balloonsappearing above and/or on-top-of later-created balloons. For example,balloon 308 is the top-ranked balloon among balloons 308 and 318, in theembodiment depicted in FIG. 3E, because the “Le Grill” keyword appearsbefore the “Central Cinema” keyword in group IM session 300. In someembodiments, however, balloons having the same number of “yes” votes areranked in accordance with respective “neutral” and/or “no” votes, and“no” votes can have the same of greater weight than “neutral” votesdepending on the specific embodiments. In such embodiments, balloonsassociated with identical votes or votes of equal cumulative weight canbe ranked in chronological order.

In the embodiment depicted in FIG. 3F, group IM session 300 includesmessages received in response to message 250. For example, user 230sends message 252, user 234 sends message 254, and user 216 sendsmessage 256 in response to message 250. Messages 252, 254, and 256variously indicate agreement with the alternative proposal presented inmessage 250. Accordingly, group IM session analysis software 132registers votes and updates group IM session model 136 as describedherein.

FIG. 3G depicts instance 302 of the balloon assistant mode, as presentedin topic summary pane 204, after group IM session model 136 is updatedbased, at least in part, on message 256. As a result of votes registeredbased on messages 252, 254, and 256, balloons 314, 316, and 318 are thetop-ranked balloons of the respective keyword types. In variousembodiments, group IM session analysis software 132 associates “yes”votes with a different keyword without registering a “no” vote for thekeyword, of the same keyword type, that was previously associated withthe “yes” vote. In the example depicted in FIG. 3G, balloon 306, isranked higher than balloon 304 because balloon 304 is associated withone “no” vote from user D, as depicted in FIG. 3C, and only “neutral”votes from users 216, 230, and 234 (i.e., users A, B, and C) subsequentto message 256. In this example, balloon 306, however, is associatedwith one yes vote from user 238 (i.e., user D).

FIG. 3H depicts instance 302 of the balloon assistant mode, as presentedin topic summary pane 204, after the initiator selects the “Inactivateballoon assistant mode” option from menu 212 of user interface 200. Inembodiments like the embodiment depicted in FIG. 3H, user interface 200presents a “conclusion” of a group IM session (e.g., group IM session300) after the initiator inactivates the instance of the balloonassistant mode (e.g., instance 302). A “conclusion” of an instance ofthe balloon assistant mode is represented by the top-ranked keyword(s)(i.e., balloons) prior to the inactivation of the instance. In theexample, depicted in FIG. 3H, “Next Sunday” was the top-ranked keywordof the “when” keyword type, “Central Cinema” was the top-ranked keywordof the “where” keyword type, and “Movie” was the top-ranked keyword ofthe “what” keyword type. Collectively, balloons 314, 318, and 316represent a plan, among at least some of the participants in group IMsession 300, to meet next Sunday for a movie at the Central Cinema.Communications server 130 and/or one or more of client devices 110archives the conclusion of instance 302 of the balloon assistant mode sothat user(s) of (i) client devices 110 or (ii) the respective clientdevice(s) can view the conclusion on user interface 200 (i.e., userinterfaces 112) by selecting archive shortcut icon 214. Any user ofclient devices 110 can initiate a new instance of the balloon assistantmode in group IM session 300 following the inactivation of instance 302of the balloon assistant mode.

FIG. 4 is a flowchart depicting operations for summarizing andvisualizing information relating to a topic of discussion in a groupinstant messaging session on a computing device within the computingenvironment of FIG. 1, in accordance with an embodiment of the presentinvention. More specifically, FIG. 4 depicts operations 400 of group IMsession analysis software 132 on communications server 130.

Group IM session analysis software 132 receives a message (operation402) and extracts one or more keywords from the message based, at leastin part, on natural language processing and/or text mining algorithms,as described herein (operation 404). In some embodiments, keywords arealso extracted based on an IM topic template, as described herein.

Group IM session analysis software 132 determines whether or notextracted keywords indicate a new proposal (decision 406) based, atleast in part, on natural language processing and/or text miningalgorithms, as described herein. If group IM session analysis software132 determines that one or more of the extracted keywords indicate a newproposal (i.e., they are new keywords; decision 406, YES branch), thenew keywords are added to group IM session model 136 and are associatedwith respective keyword types (operation 408). If group IM sessionanalysis software 132 determines that none of the extracted keywordsindicate a new proposal (decision 406, NO branch), decision 410 isperformed.

Group IM session analysis software 132 determines whether or not thereceived message indicates agreement or disagreement with any keyword(s)included in group IM session model 136 (i.e., includes one or morevote(s)) and accordingly registers votes as described herein (decision410). If group IM session analysis software 132 determines that thereceived messages does not include any votes (decision 410, NO branch),decision 424 is performed. Persons of ordinary skill in the art willunderstand that a message that includes no new proposal and includes noindication of agreement or disagreement with a keyword (i.e., with anexisting proposal, a least in part), the message is not relevant to thetopic described by group IM session model 136. If group IM sessionanalysis software 132 determines that the received message includes“yes,” “no,” and/or “neutral” votes (decision 410, YES branch), group IMsession model 136 is updated accordingly and decision 412 is performed.In decision 412, group IM session analysis software 132 determineswhether or not the vote(s) trigger any opposition limits (e.g., if anopposition limit thresholds is exceeded, as describe herein). If anopposition limit is triggered (decision 412, YES branch), group IMsession analysis software 132 removes respective keywords from group IMsession model 136 (operation 414). User interfaces 112 of client devices110 update accordingly. If an opposition limit is not triggered(decision 412, NO branch), group IM session analysis software 132determines whether or not the vote(s) reorder/re-rank the keywordsincluded in group IM session model 136 (i.e., whether balloons need tobe reordered on user interfaces 112; decision 416). If group IM sessionanalysis software 132 determines that the vote(s) reorder/re-rank anykeywords (decision 416, YES branch), group IM session analysis software132 updates keyword positions in group IM session model 136 accordingly.If group IM session analysis software 132 determines that the vote(s) donot reorder/re-rank any keywords (decision 416, NO branch), group IMsession analysis software 132 updates vote counts associated withrespective keywords in group IM session model 136 (operation 422). GroupIM session analysis software 132 also updates the vote counts if thevote(s) reorder/re-rank any keyword. As described herein, the rank/orderof keywords of various keyword types is reflected in the relativeposition of respective balloons on user interfaces 112. Group IM sessionanalysis software 132 can also perform decisions 412 and 416 andoperations 414, 420, and 422 in response to receiving voting informationthat is not associated with a text or voice message (e.g., if a userdrags a balloon up or down relative to other balloon(s) of the samekeyword type on user interface 200).

In operation 424, group IM session analysis software 132 queriesdatabase 134 for a new message and iteratively performs operations 400until the initiator deactivates the instance of the balloon assistantmode.
